The shooting happened Sunday evening at the Pablo Davis Elder Living Center after police say the 65-year-old suspect had an argument with his girlfriend that ended their relationship.

The man then got a rifle from his apartment and began searching for two people he thought were responsible for the end of his relationship, according to investigators. First, he shot a friend of his ex-girlfriend, a 54-year-old woman, one time, investigators say. She was pronounced dead on arrival at Henry Ford Hospital in Detroit. Second, he shot a 65-year-old woman multiple times, investigators say. She was pronounced dead at the scene. Detroit Police spokeswoman Kelly Miner on Monday said names are not being released because police are still trying to notify next of kin.

The ex-girlfriend was not targeted by the shooter. Police combed through the complex Sunday night and did not find any other victims.

The suspect is being held by police. Miner said investigators are still preparing a case and more information about the suspect's arraignment will be available later Monday.
